In a first-ever televised event, King Charles III formally proclaimed the current monarch of the United Kingdom. Prince Charles automatically became king on September 8, the day after Queen Elizabeth passed away. On Saturday, an official ceremony was performed to formally announce King Charles as the new monarch, two days after the Queen's passing.

The proclamation was read to the Council, which consisted of senior Cabinet officials, judges, and leaders of the Church of England in the palace's Picture Gallery. Prince William, who was present in his first formal capacity as Prince of Wales, and Queen Camilla were also present. As reported by People, the Council read, "The crown of the United Kingdom of Great Britain and Northern Ireland is solely and rightfully come to the Prince Charles Philip Arthur George." 

King Charles III delivered his Declaration in front of the throne while clad in a tailcoat and black tie for the occasion. Speaking on assuming the responsibilities after his mother's passing, King Charles remarked,  "I take this opportunity to confirm my willingness and intention to continue the tradition of surrendering the hereditary revenues, including the Crown Estate, to My Government for the benefit of all, in return for the Sovereign Grant, which supports My official duties as Head of State and Head of Nation."

The lengthy two-part ceremony barely lasted forty minutes. Even though the legal accession has already occurred, a separate coronation ceremony is still scheduled for months from now. Following Liz Truss, the current UK Prime Minister, William and Queen Camilla signed the Accession Proclamation at the ceremony.
